Abstract: An antenna correcting system is provided. The antenna correction system compares amplitudes of antenna signals that are emitted or received respectively by a plurality of antenna units with each other to select one of the amplitudes as target amplitude. The antenna correction system corrects the amplitude of each of the antenna signals according to the target amplitude. As a result, the amplitudes of the antenna signals are the same as each other or approximate to each other. After the amplitudes of the antenna signals are corrected, the antenna correction system compares phases of the antenna signals with each other to select one of the phases as a target phase. The antenna correction system corrects the phase of each of the antenna signals according to the target phase. As a result, the phases of the antenna signals are the same as each other or approximate to each other.

Abstract: A microstrip antenna includes an insulating carrier, a circular body, two circular feeding points, a grounding element, and a power divider. The circular body has a first center and a radius. The two circular feeding points are surrounded by the circular body and are not connected. The two circular feeding points can produce a capacitive effect with the circular body. Each of the two circular feeding points has a second center, and a shortest distance between the second center and the first center is less than ½ of the radius. The grounding element is disposed on the insulating carrier. The power divider can generate a phase difference of 90 degrees between the two circular feeding points.

Abstract: A heading and attitude correction method and a heading and attitude correction system are provided. The method includes: obtaining attitude data in a period of time; performing a linear regression analysis on the attitude data and time points in the time period to obtain a regression line and a standard deviation; obtaining a deviation value between the attitude data and the regression line at each of the time points; excluding the attitude data for which the deviation value is greater than or equal to at least twice the standard deviation; grouping the attitude data according to a grouping value to form clusters; comparing a total quantity of the attitude data in each of the clusters, and defining one of the clusters with a largest total quantity as an ideal cluster; and calculating an average of the attitude data in the ideal cluster as a reasonable attitude data.
